This article explores how courts continue to apply and refine the &ldquo;some basis in fact&rdquo; test for certifying common issues in class actions. Recent decisions illustrate that while expert evidence is not always required, plaintiffs must provide sufficient admissible evidence to support both the existence of common issues and their class-wide resolution. The rulings reinforce certification as a meaningful screening tool and provide guidance on evidentiary expectations going forward.

The Ontario Court of Appeal&rsquo;s decision in <em>Binance v. OSC</em> clarifies the limits of the OSC&rsquo;s investigative powers and the Charter protections available in securities investigations. While the Court rejected a constitutional right to challenge a summons before compliance, it found the summons issued to Binance overbroad and unconstitutional. The ruling offers important guidance for market participants on regulatory scrutiny, the scope of document production, and the viability of judicial review.
